Brock Lesnar's return at WWE SummerSlam left everyone stunned, as no one expected The Beast Incarnate to return to the promotion and attack John Cena following his loss to Cody Rhodes. Recently, Tommy Carlucci gave his take on the former UFC star's return.Brock Lesnar was not expected to return to the Stamford-based promotion after his name appeared in the Janel Grant lawsuit. The Beast Incarnate was reportedly removed from creative plans before Royal Rumble 2024, and the company didn't mention him on television for a long time.On Behind The Turnbuckle Studios' The Last Word, ex-WWE employee Tommy Carlucci said the real reason behind Brock Lesnar's comeback was The Rock's refusal to return. The veteran added that John Cena's promo on SmackDown and The Final Boss' potential refusal to show up led to The Beast Incarnate's return at the event, which might have been a last-minute decision."I think The Rock said, 'Sc**w you,' maybe at the beginning of the week. He said, 'Sc**w you,' I'm not showing up, and Cena said, 'Why am I playing this freaking role? I don't even like it. I'm going out there. I'm cutting a promo...' I think the Brock [Lesnar] thing was a last-minute thing. You know how fast they can get things done. Get a jet, sign a contract, and they cleared him. I think it was a last-minute thing," Carlucci said.
